Was ist das Web 2.0?

Here’s how ideas can start in Silicon Valley, rocket around the world, and find their way right back here to the Valley.

Tim Bonnemann, a German Web project manager, moved to San Jose last May and loved all the social networking that took place. Events like “Mobile Monday,” “Tag Tuesday” and “Wiki Wednesday” brought together end users, developers, venture capitalists, entrepreneurs, journalists, inventors, students and anyone else who might be interested.

Bonnemann visited Germany last November, and found nothing similar. So with a few online postings, he got the ball rolling, and it caught on in short order, with Web Mondays taking place around the country, including six of the 10 largest cities.

“It’s total stealing of concepts that evolved in Silicon Valley and taking them elsewhere,” Bonnemann, who has moved back to Silicon Valley, told me at WineCamp in Calaveras County last month.
